Examine figure A on the left. Any two conductive plates, separated by a resistive material form a capacitor. The two metal plates in figure A form a capacitor with air as a dialectric. Now, if we connect a coil across the two plates, we form a tank circuit, which will act as a parallel resonance at some given frequency. We know that a wire which carries a current will generate a magnetic field around it. This tells us that the wire is inductive, and will act as a coil.
So if we connect a straight piece of wire (B) between the capacitor plates, we have still created a resonant circuit. Now if we continue to add wires (C), it will have the same reaction, as if we continued to add coils in the circuit. In theory, we can continue adding wires until, in effect, the individual wires form one solid piece of tubing (D) around the capacitor. This would still be a resonant circuit at some given frequency.
